With iOS 4 release today Apple updated the iBooks app for the iPad. There are many improvements and new features, most noticeably, now PDF files are easily synced to the iPad via the iTunes just like ebooks, and there is a separate tab in the iBooks that puts the PDF files on a separate book shelf.
